This was our first time in Bangkok, but it actually felt like visiting a good friend. Koblul is an awesome host, and her breakfasts are extra-local. Perfect choice for those interested in authentic Thai food. Also, the house is located in the heart of the old town, and you can walk to all the key points (or take a tuk-tuk). It took us around 10-20 min to walk to the Royal palace, at least five different temples (all of them are simply breathtaking), China Town, and also it is a 5-min walk from the airport bus stop. There is a beautiful park not far from the house, and many people are jogging and playing sports games there. There is a boat station and MRT nearby as well, and we used these options to travel around the city.
The room is nice and local, although it is really noisy sometimes, as the traffic outside is very active. We used earplugs, though, and it was not a big problem. Anyway, this place is a perfect chance for you to explore the real life of Bangkok and feel its spirit. We stayed there for ten days and enjoyed it a lot.
